Re: Using the Indexed Attribute in the Scope of the Iterate Tag

[dhay]

If you search the archives you'll find some examples I posted a while back.  You
also need to make sure you are using Session scope for your beans, or recreating
them when you submit so Struts can populate them.

Cheers,

David

Subject:  Using the Indexed Attribute in the Scope of the Iterate Tag




Hi,
  My search displays a table of items. Each row will have edit button so
user can edit a particular row and save it. But problem i am unable to read
values of the row user edited.
JSP looks like this.





    


   


 
   


Any ideas or sample code.
Thanks in Advance.

I work with a guy who has this same problem.  Maybe he can help you :-)

All

I figured out a solution myself... though it may not conform with the
preferred Struts patterns.  Here's how I did it, for the archives:

In short, I render the HTML Input tag 'by hand' rather than using Struts
 tag.  Then I add code in the action class 'submit' case
to put the parameter values in the form.

Here's the JSP:



... other HTML, probably table rows & such ...


   checked
   

   name=checkedListItems type=checkbox value=>

... other HTML  ...



Notes:

* This accesses the collection, myform.mylist.

* The objects in that collection must have a "boolean getEnabled(int
  idx)" method.

* Notice that I'm rendering the same parameter name
  "checkedListItems" for each checkbox, but the value is set to the
  collection index.  If the 3rd and 5th items are checked, I'll get
  a request parameter like so:

"checkedListItems" = { "2", "4" }

* Alternately you could leave the value set to "true" or "1" and
  construct a fancy parameter name.  Then you'd get this in the
  request.

"checkedListItem[2]" = { "true" } "checkedListItem[4]" = {
"true" }

  This approach seems more like the documented "indexed" attribute.
